Cisco Switch QOS Dscp Mapping Table

1.3.6.1.4.1.9.9.580.1.2.4

This table always has 64 entries, one for each DSCP value. The table contains four mappings from the DSCP value assigned to a packet. One mapping is to the egress CoS to be stored in the layer-2 frame headers for output on 802.1Q or ISL interfaces. Another mapping is to the EXP value to be stored in MPLS label. The other two mappings are to the remarked (or 'marked down') DSCP values which are used when a policer requires that a packet's DSCP value to be modified. Of these two mappings, one is for a normal burst, and the other is for maximum burst.
